I took the description below from another website because it's better than mine. Anyone ever get this? I've had it about five times. These people say it scares them. I think the first time it kind of scared me, but this last time about a week ago it was really cool, I felt like I was hanging onto my pillow to keep from falling off the earth, but it wasn't scary at all.
"I also experienced this phenomenon as a child and the memory of it has remained vivid for 55 years. (I was 5 years old when it happened) I was niether ill nor had any fever. It started by a feeling of growing bigger and bigger but lighter and lighter until i was so big I filled the whole universe. The sensation was acompanied by a low throbbing which I can only assume was my heart beating but it seemed to consume me in its sound. I could not move although I was so lightweight, only to expand further. Suddenly my whole being rushed down in size so fast that it took my breath away. I grew heavier the smaller I got until I was so small I could not be seen but my weight was extraordinary so much that I felt I would just fall through anything, straight through the centre of the earth and continue falling forever. I enjoyed this feeling and was not afraid of it. I have no idea what caused it but it has been with me for the whole of my life. When I was tiny and heavy I saw everything in the universe, well it seemed that way at the time."
Please help me experts of getbig.
